摘要

电价多解情况的出现将为实时市场的出清带来困难，有必要从理论上对其发生条件进行研究，并建立高效判定方法以提高实时定价效率。文中对节点电价多解情况的判定机理进行了深入分析和研究，基于市场出清问题的物理特性和数学特征，提出了退化、对偶问题多解与节点电价多解三者之间明确而严格的数学关系，基于所获判定机理建立了电价多解情况的完整有效判定流程，最终利用算例进行了判定方法对比以及有效性与适应性验证。

Abstract

The emergence of multiple solutions for electricity price will bring difficulties to the clearing of the real-time market. It is necessary to theoretically study the occurrence conditions of happening and establish high efficient judgment method to improve real-time pricing efficiency. In this paper

the judgment mechanism of multiple solutions for electricity price is deeply analyzed and studied. Based on the physical and mathematical characteristics of market clearing problems

a clear and strict relationship between degeneracy

dual problem and multiple solutions of nodal electricity price is proposed. According to the obtained judgment mechanism

a complete and effective judgment process of the multiple solutions for electricity price is established. Finally

the comparison of the judgment methods and the validity and adaptability verification are carried out by the case study.
